Distribution Automation Control

DNA ES hero

SEL Engineering Services provides distribution automation control solutions that improve reliability, increase operational efficiency, and reduce operation costs.

We offer an engineered solution, in which the primary deliverable is a fully configured and commissioned SEL distribution automation controller (DAC)—an autonomous device which uses secure communications to control and coordinate with devices throughout the system. The DAC is a perfect solution for automatic restoration schemes.

With distribution automation engineered by SEL, you can:

  • Prevent outages—Isolate faulted sections and quickly restore power to the rest of the distribution network.
  • Improve reliability—Improve your system’s CAIDI (Customer Average Interruption Duration Index) and SAIDI (System Average Interruption Duration Index) metrics.
  • Save time and money—The SEL automation controller can collect advanced data from IEDs throughout the system, enabling predictive maintenance and preventing costly equipment failures.

Automation Tailored to Your Needs

The core of each DAC solution is an SEL Real-Time Automation Controller (RTAC) with control logic that is configured by our engineers specifically for your system.

We can design and implement a broad set of functionalities or a subset that addresses your specific needs. Our scalable, modular approach to distribution automation allows you to add new capabilities as the demands on your system change over time.

The DAC can integrate with the IEDs already in your system—and we can also provide protective relays, recloser controls, secure communications, and other equipment as part of the solution, depending on your needs.

In addition to fault location and automatic network restoration, the DAC can:

  • Automatically collect data from devices, including metering, monitoring, and diagnostics.
  • Integrate with SCADA or an advanced distribution management system (ADMS).
  • Use acSELerator Team SEL-5045 Software to enable dynamic disturbance and fault recording (DFR) capability that exceeds NERC PRC-002-2 requirements.
  • Provide secure remote access to devices and system controls.

Reliability Is Assured

To ensure reliability, we do an in-depth study of your distribution control system before configuring the control logic in the DAC. The final step before commissioning is a rigorous factory acceptance test, which your operators and engineers are invited to attend.

The factory acceptance testing features simulated field devices and runs through a multitude of test scenarios to verify system performance, so you can be sure that your SEL distribution automation solution will do precisely what you need it to—the first time and every time.

Products You Can Rely On

SEL manufactures the electric power industry’s most durable and reliable devices.
